anyone tried to run a different intake tube w/ stock airbox ?

First off dyno's numbers can be skewed a number of ways.  A lot .if the tuned and non tuned runs where not back to back.  Secondly, most dyno's make the runs with the hood open.  This is not how cars run on the street.  Only way to really test heat soak is in a live "on road" environment.  JMO.

VERY GOOD point about dynos with hood open  ... its easy to  direct cool air to  the intake and reduce engine bay heat .

All true... dyno results can be changed if conditions are changed...
but back to back dynos in the same conditions still do a pretty good job of demonstrating whether their are any performance differences in different configurations or no gain... True this is shown in the difference between the two configurations performances although not necessarily the absolute numbers.  (heck it's why we race!). Check out this thread as well as just this post... food for thought about practical application and testing of dyno and street conditions adjusting the same variable in each one.

The test of the Box vs Wide Open Intake.  If anything, having the hood open with a fan on should have given an advantage to the Wide Open Intake.  Yet, it was still < 3HP higher.  That puts them just about even in my book.  I have to say that Ford did a great job on this one.  The only thing to improve would be to trim the outer hood molding ala BPD.
